Internet Information Services is not installed...

Hello!

I have an issue I've never run into.  I have a client that deploys patches with WSUS, and one of the servers he deployed to happened to be a SharePoint WFE (which is Windows NLB with another server that had no problems) on Windows Server 08 R2.  After the latest run of patches were installed, SharePoint stopped working - no more browsing to either User sites or to Central Administration.  As with SharePoint patches, you do the ol' SharePoint Products configuration Wizard, but it came up with the error:

Internet Information Services is not installed.  You must have Internet Information Services installed to run the Configuration Wizard.

And then it closes.  Checked IIS services - all required are running.  I figured I'd uninstall SharePoint - no can do, because PSConfig (part of the repair and uninstall process) has to run, and it can't because it thinks IIS is not installed.  I uninstalled IIS and the Application Server Role, then reinstalled them - same issue.  I honestly don't know what more to do.  Anybody face this before?

Thanks!

Gene.
